SHOE ron FURNITURE-Lues.

To all 'whom/t may concern:

Be it known that I, ADAM E. SoHA'rz, of Mount Vernon, in the county of I/Vestchester and State of New York, have invented certain new and useful Improvements in Shoes .fpr Furniture-Legs, whereof the following is a specification, reference being had to the -accompanying drawings.

The object of the invention is to provide a simple and inexpensive device of the character indicated, which may be easily applied to the legs of chairs or other articles of furniture, and which when once applied is so securely attached to the same as not to subsequently become detached therefrom.

The shoe is, formed by stamping-up a. disk of sheet metal inioa convexity whicl. forms the sliding surface of the shoe. Around the edge oi the convex portion and at right angles to its sliding surface are formed three or more flattened prongs with side spurs near their points. By properly spacing thesevflattened prongs around the edge of the convex body of the shoe such variation in the planes of the prongs is obtained as insures' the proper embedding of one or more of them into the wood, with such firm engagement of the spur in the wood as to prevent subsequent detachment.

In the accompanying drawings, Figure I, is a perspective view of ashoe embodying my invention.` Fig. II, is a similar view, with parts broken away, showing the shoe as applied to the end of the leg of the piece of furniture, such as a chair. Fig. III, is a cross section on thel line III, III, Fig. II, illustrating the w'ay in which the prongs, or some of them, attach themselves within the wood at the end' of the furniture leg.

The body of the shoe is stamped-up from a piece of sheet metal so as to take the form of a convexdisk 1, the center of its convexity forming the sliding surface of the shoe. Around the rim or' this convex disk, integral -with it, and projecting at right angles to the sliding surface of' the shoe are formed flattened prongs 2, 2, .2. For reasons which will hereinafter be made clear, there should l be not less than three of these prongs. Each ne; rong isv pointed and provided with opposed despurs 3, 3, forming a spear head at the end of the prong. These spear headed fiat- "l ten'd propgsrpeing preferxftllythrce in num- Speci'cation of Letters Patent.

Serial No. 625,375 Y ber and spaced equi-distantly around the rimv of the conVeXed disk necessarily lie in dlfferent planes, related to each other as the sides of an equilateral triangle. The purpose of the spurs on the sides of the prongs is to hold the prong, when driven into the wood, from becomingsubsequently detached therefrom, which accident the prongs -prevent. by embedding themselves in the Wood, which by its natural resiliency surrounds and takes hbld upon the point of each spur. As these shoes are intended for the ends ofthe leg of a piece of furniture, which in almost all cases is cross cut to the grain of the wood, it is obvious that the Hattened prongs must enter the wood in the direction of' its grain. As shown in Fig. III, thc grain of the wood under these circumstances presents the appearance of more or less concentric layers surrounding a center which except in very rare instances, will never be the center of the furniture leg. If a flattened prong, whether 'provided with spurs orV not, isinserted into a cross cut wooden surface in such a way that the plane of the flattened prong coincides with the dividing plane between two of the concentric layers orming the wood, the tendency of the prong is to cleanly divide the two layers from each other, and the resiliency of the wood under these circumstances is not sufficient to thereafter completely 'embed the spurs formedv on the edges of the flattened prong, for the separation of the layers of of the prong as shown at 5, in Fig. III. But if the same -fiattened prong be driven into the same piece of wood in such a way that its plane is in angular|relation to the layers of the Wood, the resiliency of the wood is much greater, and spurs formed on the sides of the prongs are embedded and firmly caught, as shown at 6, 6, in Fig. III. By providing the shoe with three or more. of these flattened prongs in different planes, it is insured that one or more of the prongs will so enter the wood as toenable the spurs to properly embed themselves to prevent thel detachment of the shoe.

Having thus described my invention, I claim: l
